Genes affected
EDN3 (HGNC:3178): (endothelin 3) The protein encoded by this gene is a member of the endothelin family. Endothelins are endothelium-derived vasoactive peptides involved in a variety of biological functions. The active form of this protein is a 21 amino acid peptide processed from the precursor protein. The active peptide is a ligand for endothelin receptor type B (EDNRB). The interaction of this endothelin with EDNRB is essential for development of neural crest-derived cell lineages, such as melanocytes and enteric neurons. Mutations in this gene and EDNRB have been associated with Hirschsprung disease (HSCR) and Waardenburg syndrome (WS), which are congenital disorders involving neural crest-derived cells. Altered expression of this gene is implicated in tumorigenesis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]

The p.Thr185Met variant in EDN3 has not been previously reported in individuals with pulmonary disease, but has been reported in one Japanese individual with la te-onset hearing loss (Miyagawa 2013). This variant has been identified in 4/165 12 South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exa c.broadinstitute.org; dbSNP rs368327225). Computational prediction tools and con servation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Thr185Met variant is un certain. -

Variant summary: EDN3 c.554C>T (p.Thr185Met) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.6e-05 in 251420 control chromosomes (gnomAD). c.554C>T has been reported in the literature in one Japanese individual affected with late-onset hearing loss (Miyagawa_2013). This report does not provide unequivocal conclusions about association of the variant with Waardenburg Syndrome Type 4B. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One ClinVar submitter has assessed the variant since 2014: the variant was classified as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 185 of the EDN3 protein (p.Thr185Met). This variant is present in population databases (rs368327225, gnomAD 0.02%). This missense change has been observed in individual(s) with late-onset deafness (PMID: 23967202). ClinVar contains an entry for this variant (Variation ID: 228660). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
